The dye mapping towsled has a long tail and passive tail
fins. The fins stabilize the attitude while underway.
The tow point is behind the center of drag at the bow,
reducing pitch from cable tension changes. The cable is
attached to a bar reaching down to a pivoting connection.
The vehicle is intended to pitch in response to forcing
at the A-frame such that it follows its bow, in other words,
minimizing the angle of attack through the water.
The orange emergency recovery floats impede the flow but
provide peace of mind and counterbalance the tail.
